Effect of Bilateral Internal Mammary Artery Ligation on Coronary Circulation in Dogs
The internal mammary arteries of dogs were ligated bilaterally subsequent to surgical narrowing of the circumflex arteries. Six weeks later measurements of retrograde circumflex flows were made to assess the extent of collateral development. The results when compared with control dogs indicated that internal mammary ligation did not significantly improve the blood supply to the myocardium.
